While she's not necessarily the best character in terms of towers or fighting ability, the Series EV is an awesome support class to play as. The EV can use two weapons at a time, but unlike the Jester who can do the same with any weapons, EV is limited to Apprentice staffs and Huntress guns, giving her more options for ranged weaponry combos than most other classes can. The best way to play this character is probably to give your towers a lot of health, as she has arguably the best, and most versatile wall towers in the game, not to mention she's the only character with walls that can defend against projectiles. Archer enemies are normally the bane of a player's existence, but EV fixes the problem. Maybe save this one for later, but don't wait too long to get it.
